Hello,
I connected my 4 MPPT through https://www.amazon.com/dp/B09TJMLNG1?psc=1&ref=ppx_yo2ov_dt_b_product_details and can confirm from my mac that I do have 4 serial ports and there is transmission happening.
When I add that usb to my ekrano, it does not pick up the MPPTs. I have confirmed it sees the 4 serial ports:
ls -d /service/vedirect-interface.ttyACM*
/service/vedirect-interface.ttyACM0 /service/vedirect-interface.ttyACM1 /service/vedirect-interface.ttyACM2 /service/vedirect-interface.ttyACM3
I have also confirmed the properties of the serial port:
